I'm still confused..According to that link, it's a 235. You guys say a 235 wasn't standard on a 1950 3600. But that page reads 1950 3600 235. ??

Is the engine original or no? 216 or no? I'm getting things jumbled up with these different pages.

Thanks for the videos DADS. When we get a chance to remove the valve cover I'll record a video of the noise we hear.
AFA the sound going away with the clutch, I didn't notice. I'll have to see next time were out/look at my video closer.
If the sound goes away with the clutch depressed, that signifies...........?
